Long term follow-up is needed to determine whether current Mobile Bearing revision Total
Knee Arthroplasty (TKA) designs will improve implant longevity. The potential advantages of
mobile bearings in the revision TKA setting include reduction in polyethylene wear,
decreasing fixation stresses, and protection of the constraining mechanisms. Several studies
have reported satisfactory clinical results after revision total knee arthroplasty but no
study with a large number has specifically addressed the clinical outcomes after revision
total knee arthroplasty using the mobile bearing design

Failure modes of revision total knee arthroplasty (TKA) that include prosthetic loosening
and damage to constraining mechanisms often require revision TKA. Mobile bearing revision
TKA components have been developed in hopes of lessening these failure mechanisms. Our
purpose is to evaluate the use of mobile bearings in revision TKA.
Retrospective clinical and radiographic evaluation of 340 revision mobile bearing TKAs using
the PFC Sigma and LCS posterior stabilized rotating platform implants (Depuy, Warsaw, IN)
will be performed. Indications for revision include instability, loosening, arthrofibrosis,
chronic hemarthrosis, failed patellofemoral replacement, failed unicompartmental knee
replacement, infection reimplantation, and supracondylar fracture nonunion.

Inclusion Criteria:
Requiring a revision of a primary knee replacement. Indications for revision include
instability, aseptic loosening, failed unicompartmental knee replacement, infection
reimplantation, arthrofibroisis, chronic hemarthrosis, failed patellofemoral replacments,
and non union of a supracondylar femur fracture.
Exclusion Criteria: None since they have all required a revision.
